Watchdog Man has been shown to be very blunt and nonchalant. He also has a habit of wearing his costume all the time even during bath time. His table manners are also pretty bad since he eats like a dog and is never seen using a fork or spoon, he also sleeps like a dog too.

Like a dog, he is only protecting his territory, Q-city, during his hero job, stating himself that, as long as he can defend his city he is content. One example is when he immediately stopped pursuing Garou after their battle reached the city limit, thus making it possible for Garou to escape.

As the higher-ups of the Hero Association discuss the status of various cities, Watchdog Man was mentioned, as the hero in charge of Q-City. His report states "All quiet here". The suits are concerned about Watchdog Man's attitude, but admit that he can handle the dangerous city.[4]

Garou finds Watchdog Man relaxing in the Watchdog Man Plaza.[6] Before he can attack, an invasion from the Monster Association arrives at the plaza. Watchdog Man quickly dispatches all of the monsters and rips them apart with great haste, while Garou observes him. Garou then attempts to attack Watchdog Man while the hero is sitting.[7]

Watchdog Man then engages in battle with Garou. Unfortunately for Garou, Watchdog Man is shown to be far superior to him in speed and strength, as even though Garou remarked his technique was like that of a wild animal, Garou was still unable to properly read his movements and was ultimately defeated, even after Garou used his most powerful technique: the Water Stream Rock Smashing Fist. All the while, his face remained stoic and emotionless.[8]

Watchdog Man and the other S-Class heroes were invited to a hot spring resort, after the Dark Matter Thieves failed invasion. While at the hot spring, he was questioned by Metal Bat about his whereabouts, only to state he went to protect his city. When Zombieman was found murdered and Child Emperor was trying to find the culprit, Watchdog Man was asleep and couldn't be woken up.[1]

As an S-Class hero, Watchdog Man is extremely powerful. A testament to his prowess is that he was left in charge of Q-City, which is considered to be the most dangerous city in the country. In his early days as a hero, he managed to rip off the head of a Demon-level monster without incurring an injury.[9] According to the Hero Association, Watchdog Man has taken out Mysterious Beings faster than any other hero.[4] Watchdog Man is also strong enough to defeat Garou effortlessly without changing his deadpan expression. However, a contributing factor to this is that Garou at that time lacked experience in fighting against non-humanoids as Watchdog Man fights like an animal rather than a human, and also because Garou himself underestimated the hero due to his lack of techniques.

Immense Speed and Reflexes: Watchdog Man is extremely fast, being able to rip apart multiple monsters in a short amount of time.[10] He holds the record for fastest monster elimination. He is also able to block multiple attacks from Garou, then retaliate at a speed that Garou could not counter.

Master Hand-to-Hand Combatant:Garou described Watchdog Man's fighting style as that of a beast or a monster rather than a human. Garou also noted that Watchdog Man lacks any special techniques or weapons, relying only on simple hand-to-hand combat.[11] However, Watchdog Man's skills are demonstrated to be rather powerful, being able to counter Garou's martial art techniques, including his Water Stream Rock Smashing Fist. As a result, he can counter all of Garou's movements perfectly, since Garou's techniques are designed to be used against human targets, not monsters, as well as the fact that Bang has yet to teach him how to fight monsters. When he countered Garou's attacks, his blocking resembled the dog-like behavior of giving his paw for a handshake.[12]
